Adaptive /Assistive hardware Hardware to adapt the computer’s capability for input, processing, and output for students of different needs (e.g., touch screen, voice-recognition devices). Address book, e-mail A small database in an e-mail program in which you store e-mail addresses for individuals and groups with whom you correspond. Address, Internet See Internet IP address. Animation Representations of an object in motion. Application A program that helps the user accomplish a specific task; for example, a word processing program, a spreadsheet program, or a file transfer protocol client. Application programs are distinguished from system programs (which control the computer and run the application programs) and utilities (which are small helper programs). Arrow keys Keys on a keyboard that move cursor Left, Right, Up or Down. AU A sound file format, originally for Sun UNOIX systems, now also supported on Personal Computers and Macintoshes. AVI (Audio Video Interleaved) Microsoft’s video for Windows
movie format, used for storing video with audio. Bitmap In bitmap graphics, an image is displayed on the screen as a collection of tiny squares called pixels, which together form a pattern. Each pixel in the image corresponds with one or more bits; the number of bits per pixel determines how many shades of gray or colors can be displayed. BMP A bitmapped graphics file in Windows format. Boolean In computer science and digital electronics, this term means an expression with two possible values, “true” and false, ”. The most common Boolean operators are AND, OR and NOT. Boot up Loading operating system software into memory to start up a computer. Also called starting up. Browser A program that allows users to read hypertext documents on the World Wide Web and navigate between them. Examples are Netscape Navigator, Lynx, and Microsoft Internet Explorer. Byte A byte is 8 bits; one byte can represent a single character. On most computers, the byte is the basic unit of addressable memory. On IBM Mainframes, a word is 4 bytes (32 bits). Cache A temporary storage area for frequently-accessed or recently-accessed data. Having certain data stored in a cache speeds up the operation of the computer. There are two kinds of cache: internal (or memory cache) and external (or disk cache). Internal cache is built into the processor, and external cache is on the motherboard. When an item is called for, the computer first checks the internal cache, then the external cache, and finally the slower mail storage. Case sensitive Treating upper case letters as different characters from the same letters in lower case. Filenames or text searches that are case sensitive would distinguish between, for example, Internet and internet. Cell referencing A means of identifying and locating a cell, or range of cells, which are to be used in a formula. Predominantly applies to spreadsheet applications. Individual cells are usually identified by a column letter and a row number. For example, D12 specifies the cell in column D and row 12. CD-ROM (Compact Disc Read-Only Memory) A disk that is physically the same as an audio CD but contains computer data. Storage capacity is about 650-680 megabytes Cell A box in a spreadsheet or table where data can be entered. The intersection of a row and a column in spreadsheet or worksheet. Chat acronyms These common acronyms (and dozens more) are used in
online, real-time, typed conversation and in e-mail as a form of shorthand
communication. Clip Art Pictures provided to be copied and integrated within larger works Clipboard An area of temporary memory which is used to transfer text and graphics within a document being edited, or between documents. The data is put into the clipboard with either the “cut” or “copy” command, and then “paste” takes it from the clipboard and puts it in its new location. Compact Disk, Read-Only Memory (CD-ROM) A read-only disk that stores large amounts of data to be used by a computer. Computer-Assisted Drafting Software (CAD) Software designed to facilitate computer-generated drawings or schematics. Concept-Mapping Software Software that can graphically represent the relationships among ideas (e.g., Inspiration).

A computer designed to stay on a desk, as opposed to portable laptop and notebook designs. Desktop Publishing Software that aids in the creation, formatting and printing of documents with text and graphics. Dialog Box A box on the computer screen that can be used to enter information, set options, or give commands to the computer. The dialog box gives the user choices (such as open file, delete, save) which can be selected by clicking with the mouse. Digital Describes any system based on discontinuous data or events. Computers are digital machines because at their most basic level they can distinguish between just two values, 0 and 1, or off and on. There is no simple way to represent all the values in between, such as 0.25. All data that a computer processes must be encoded digitally, as a series of zeroes and ones. Digital archive Information stored in digital format. Directory, folder Places on a disk where you can store files and subdirectories. The organization of directories (or folders) and files on a hard drive is like the branches of an upside-down tree. The mail directory is called the “root directory”. Disk drive The device that reads from and writes to a floppy disk or hard drive. Diskette A small, portable, flexible magnetic disk used for data storage on many computers. Diskettes come in 3 ½” and 5 ¼” sizes, with several densities and formats. These disks are known as “floppy” disks (or diskettes) because the disk is flexible and the read\write head is in physical contact with the surface of the disk, in contrast to “hard disks” that are rigid and rely on a small, fixed gap between the disk surface and the heads. Diskettes may be either single-sided or double-sided. Distortion filters Add-ons to high-end graphics programs (e.g., Adobe Photoshop) that modify or distort images in a predictable or controllable way. A distortion filter might, for example, cause a picture to appear as if it had been drawn in charcoal. Domain name An Internet address in alphabetic form (for example, intel.com
or www.intel.com). Domain names must have at least two parts: the part
on the left names the organization, and the part on the right identifies
the highest subdomain. Directory levels can be indicated at the end,
separated by a slash (/). The right-hand side or end of a domain name
helps identity what type of agency or organization is hosting the site.
For example: DOS An acronym for disk operating system. The term DOS can refer to any operating system, but it is most often used as a shorthand for MS-DOS (Microsoft disk operating system). Originally developed by Microsoft for IBM, MS-DOS was the standard operating system for IBM-compatible personal computers. See also folder.

and related technologies in: Electronic mail (e-mail) A system whereby a computer user can exchange messages with other computer users (or groups of users) through a communications network. E-mail address An e-mail address has the form “person id” at “domain id.” For example, jdoe@intel.com. The company name is identified by its Internet domain name, intel.com. Embedding With an embedded object, information in the destination file does not change if you modify the source file. Embedded objects become part of the destination file and, once inserted, are no longer part of the source file. Double-click the embedded object to open it in the source program. Both embedding and hyperlinking allow you to add all or part of a new or previously created file (Microsoft Office file, sound file, video file, etc.) into a Microsoft Office file. An embedded file becomes part of the file in which it is embedded. A hyperlink simply points to the location of the original file, and opens the linked file from its saved location. Emoticons Typewritten pictures of facial expressions, used in e-mail and when communicating on the Internet, to indicate emotion. Most often producing an image of a face sideways. They are also called smileys. Enter To input by using keystrokes; a keyboard key also known as the Return key. Escape (ESC) A key used to get out of, or exit, certain actions or programs. Extension, file name The portion of a file name following the final point (period) that indicates the kind of data stored in the file. Extensions are usually from one to three letters (for example, .ppt, .doc, .au, .wav). DOS and Windows extensions must be three or fewer letters; Macintosh extensions can have more letters, or can be deleted. Fair Use A legal principle that allows portions of a copyrighted work to be used for educational purposes without permission from the copyright holder (e.g., use of portions of a copyrighted work with students by educators to illustrate a concept). FAQ Abbreviation for “Frequently Asked Questions.” Newsgroups, mailing lists and Internet sites often have a list of the most frequently asked questions about their subject, with answers. Favorites A feature in Microsoft’s Internet Explorer browser that enables the user to record URLs that will be frequently used by adding them to a special menu. The equivalent in Netscape Navigator is Bookmarks. Once the URL is on the list, it is easy to return to that Web page simply by clicking on the link in the list, rather that retyping the entire URL. Field The smallest piece of information in a database. File A collection of information stored in any of numerous forms on any of numerous devices. A file may contain programs, data, or text. File Transfer Protocol (FTP) Allows files to be transferred between Internet-connected computers. Filters Hardware or software designed to restrict access to specific areas on the Internet. Flash drive/jump drive A small, portable flash memory card that plugs into a computer’s USB port and functions as a portable hard drive with up to 2GB of storage capacity. Flash drives provide less storage capacity than external hard drives, but they are smaller and more durable because they do not contain any internal moving parts. Floppy disk See diskette. Folder On computer screens for Macintosh and Windows 95 (and above), files can be organized by placing them into folders that look like office file folders. These folders correspond to directories in DOS. Font A text formatting term: A complete assortment of printer characters in a particular type style, typeface, size and orientation. Most fonts include letters, numbers, punctuation and some special symbols. Note that the Roman (normal), Italic, Bold and Bold Italic typeface forms of any type style and size are each separate fonts. A font family is a complete set of characters in the same type style, including all sizes and typefaces, such as bold, italic and underline. Footer A text formatting term: One or more lines of text that appear at the bottom of every page. Format To arrange data in a particular manner. For example, on a spreadsheet, numbers may be displayed in many formats, including 40%, a percent format. Formula Formulas are equations that perform calculations on values in your worksheet. A formula starts with an equal sign (=). For example, the following formula multiplies 2 by 3 and then adds 5 to the result: =5+2*3. Freeware Software, often written by enthusiasts, distributed at no
charge by users’ groups, FTP (File Transfer Protocol) A protocol in the internet suite which allows a user on any computer to get files from another computer, or to send files to another computer. Function Functions are predefined formulas that perform calculations by using specific values, called arguments, in a particular order, or structure. Functions can be used to perform simple or complex calculations. The structure of a function begins with an equal sign (=), followed by the function name (such as SUM, AVERAGE, etc.), an opening parenthesis, the arguments for the function separated by commas, and a closing parenthesis. GIF (Graphics Interchange Format) A format for pictures that many browsers can display. A color-image transfer protocol developed by CompuServe, GIF format works best for graphics with contiguous areas of solid color like graphics, clip art, and drawings. GIF is the only file format that allows for animation, transparency effects, or interlacing (the graphic load gradually with a venetian blind effect). GIF files are widely used on Web pages because they provide good-quality color images in a format that takes up a small amount of space. Gigabyte 1024 megabytes. Literally meaning one billion bytes. Abbreviated GB, Gbyte or G-byte. Graphics Designs and pictures created and used by the computer and user to illustrate computer documents.

Hard copy Usually hard copy means paper, but presumably can mean any printed computer output, such as microfilm. Hardware The physical devices that make up a computer and networked system. Hard disk or hard drive The main device that a computer uses to store information. Hard disks are rigid aluminum or glass disks about 3.5” in diameter in a personal computer, and smaller in a laptop. They are coated with ferromagnetic material and rotate around a central axle. Data is transferred magnetically by a read/write head. A hard disk for a personal computer may contain as many as eight hard disks, rotating around the same axle. Header 2. A computer communications term: Control information that is added
before data HTML (HyperText Markup Language) The language of the World Wide Web used to create Web pages, with hyperlinks and markup for text formatting (heading styles, bold, italic, numbered lists, insertion of images, etc.). HTTP (HyperText Transport Protocol) The rules by which World Wide Web browsers and servers communicate. This is the protocol most often used to transfer information from Web servers to browsers, which is why Web addresses begin with http://. Home Page The first page a user sees when visiting a World Wide Web site. Home row The basic keyboard position, in which the fingers of the left hand rest on a, s, d, f, and the fingers of the right hand rest on j, k, l. ;. Hyperlink A link is an HTML document that leads to another place on
the same page, to another page on the same Web site, or to another
World Wide Web site. A browser usually displays a hyperlink in some
distinguishing way, such as a different color, for or style. When the

Mail merge Refers to generating form letters by combining one file containing a list of names, addresses, and other information with a second file containing the text of the letter. Megabyte Equals 1,048,576 bytes, or 1024 kilobytes. The text of a six hundred page paperback book would require about one megabyte of ASCII storage. (ASCII is the basis of character sets used in almost all present-day computers.) Abbreviated MB. Memory The part of a computer system that is used to run programs. The working space used by the computer to hold the program that is currently running, along with the data it needs, and to run programs and process data. The main memory is built from Random Access Memory (RAM) chips. The amount of memory available determines the size of programs that can be run, and whether more than one program can run at a time. Main memory is temporary, and is lost when the computer is turned off. It is distinguished from more permanent internal Read Only Memory (ROM) which contains the computer’s essential programs, and storage (the disks and tapes which are used to store data). In the general sense it can be any device that can hold data in machine-readable format. Also see RAM and ROM. Menu An often hierarchal list of information “trees” to sub-menus or other documents. Merge To combine two files in such a way that the resulting file has the same organization as the two individual files. For example, if two files contain a list of names in alphabetical order, merging the two files results in one large file with all the names still in alphabetical order.

It is a standard connection for digital control of musical devices. Used for synthesized music. Cannot be used for the human voice or other complex sounds. File size is usually small. Modem A peripheral device that connects computers to each other for sending communications through telephone lines. The modem modulates the digital data of computers into analog signals to send over the telephone lines, then demodulates back into digital signals to be read by the computer on the other end; thus the name “modem” for modulator/demodulator. It converts characters into a form that can be transmitted over a telephone line, and reconverts transmitted signals to characters. Monitor The TV-like screen that lets you see your computer activity and output. MPEG (Moving Pictures Experts Group) An ISO (International Standards Organization) group that sets standards for compressing and storing video, audio, and animation in digital form.

Resolution A graphics formatting term: The number of dots per inch used to represent a graphics image. The term “pixels” is also used for “dots” in this context. High resolution images look smoother and have more dots per inch that do low resolution images. The resolution of images displayed on the screen is usually lower that the of the final laser printout. Laser printers print 300 dots (or pixels) per inch or more; typesetters print 1200 dots (or pixels) per inch or more. ROM (Read Only Memory) Stored permanent systems instructions, which are never changed; It holds its contents even when the power is turned off. Data is placed in ROM only once, and stays there permanently. ROM is generally installed by the manufacturer as part of the system. Rubric A scale, guide, or continuum that is created to clarify expectations for a given projects and to give a specific feedback Scaffolding tools Scaffolding tools help student to organize and support their own investigations, and keep them from straying too far off the path of a given inquiry.
